Plus family happens now for many of us, and not later. Kids need their parents, not their money. Its a grave mistake that hurts badly your closest ones for life to prioritize excellence in 1 direction over everything else, especially them.
I'll always have endless amount of respect of people raising their kids properly themselves into mature, happy adults who know what they want in life and go for it, even if it means they just worked to live. I don't have even a cubic picometer of respect for folks who end up doing the opposite, regardless of what they achieved professionally. This world needs new generation of balanced adults much much more than some search optimized by 0.1% or some marginally improved social graph monetization.
Of course not everybody wants, needs or can create a family, that's fine but another topic, then I agree with you more.
